Shortly after casting his vote Tuesday in Palm Beach, Florida, former President Donald Trump again refused to commit to accepting the results of the presidential election unless he deems it was fair.

Trump, who continues to falsely allege there was widespread fraud in the 2020 race, attacked machine voting as “corrupt” and said a winner should be declared Tuesday night, even as election officials and experts say it could take days to count the votes.

“If I lose an election, if it's a fair election, I'd be the first one to acknowledge it,” he said. “And I think it's, well, so far, I think it's been fair.”

The Republican presidential nominee also gave testy answers when asked if he’d urge his supporters not to turn to violence if he loses and how he voted on a constitutional amendment in Florida that would legalize abortion up until fetal viability. 

“I feel very confident,” Trump said inside a recreation center gymnasium, with his wife, Melania, at his side. “We went in with a very big lead today, and it looks like Republicans have shown up in force. So we'll see how it turns out.”

Trump said he believes his third presidential campaign “was maybe the best of the three.”

Four years ago, Trump declared victory on election night despite that large numbers of mail-in ballots had not yet been counted. The former president, however, acknowledged that this time he’s been told some states “won’t have a final number for a long time.”

Trump is hosting multiple dinners Tuesday night at his Mar-a-Lago Club before he heads to his campaign’s election night watch party at the Palm Beach County Convention Center. 

“I don't know what's going to happen in terms of declaring victory, but if in normal times, I would go over to the convention center let's say at 10:00 or 11:00 or something," the former president said. "But I just don't know.”

He said he has not prepared any speeches.

Trump again voiced his frustration that it could take days before the winner is known. He has previously made baseless claims that “crooked people” are behind the delays. The former president argued all votes should be cast on paper ballots.

“They use these very expensive computers, and I'm hearing in Pennsylvania they won't have an answer till two or three days from now,” he said. “I think it's an absolute outrage, if that's the case.”

One of many reasons the nation is unlikely to know the winner quickly on election night is that Republican lawmakers in Pennsylvania, as well as in Wisconsin, refused to change the law that prevents them from processing their mail ballots before Election Day. That means mail ballots get tallied late, and frequently the results don't start to get reported until after Election Day.

Trump took exception to a reporter’s question about whether he’d preemptively condemn post-election violence to his supporters, arguing they “are not violent people.”

“I don't have to tell them that there'll be no violence. Of course, there'll be no violence,” he said.

“I certainly don't want any violence, but I certainly don't have to tell — these are great people. These are people that believe in no violence.”

The former president then snapped at the reporter.

“Unlike your question,” he said. “You believe in violence.”

On Jan. 6, 2021, a mob of Trump supporters clashed with police officers outside the Capitol before forcing their way into the building. More than 100 police officers were injured, and lawmakers were rushed to secure locations, delaying the certification of Joe Biden’s win over Trump for hours. 

The riot followed a Trump rally held near the White House, where the then president repeated false election fraud allegations and directed the crowd to march to the Capitol.

More than 1,500 people have been charged in the riot, and over 1,000 have been convicted. More than 500 suspects have been charged with assaulting, resisting or impeding law enforcement officers, and over 160 are accused of using a deadly or dangerous weapon or causing serious bodily injury to an officer. Trump has vowed to pardon Jan. 6 criminals and defendants if elected.

The former president also seemed annoyed when asked how he voted on Florida’s abortion measure, saying, “Just stop talking about that.”

He has sent mixed signals about his opinion of Florida’s six-week abortion ban but said in August he’d vote against repealing it.

The former president also said he was not feeling any additional pressure Tuesday related to his ongoing criminal cases. If he wins the election, the two federal cases against him — one related to his efforts to overturn the 2020 election and the other dealing with his handling of classified documents — are expected to be dropped by his attorney general pick. A judge dismissed the documents case in July, but the ruling is being appealed.

Trump also faces sentencing in New York after being convicted of falsifying business records to cover up hush money payments made to a porn star, as well as a Georgia case also related to his efforts to subvert the 2020 vote. As president, he would have no authority to kill those cases.

If Trump loses the election, all four cases could proceed.

“I have no pressure whatsoever,” he said. “I'm winning the cases. Those cases are all being won. The biggest case was the Florida [classified documents] case, and it's been won.”

Trump, 78, again said, even if he loses, he is unlikely to run for president again. He said he feels “sad and very fulfilled” that his campaigning career is drawing to a close.

Earlier Tuesday, Trump’s running mate, Ohio Sen. JD Vance, cast his ballot in Cincinnati. He was joined by his wife, Usha, and their three children. 

Afterward, Vance told reporters he voted for Trump and himself as well as GOP Senate candidate Bernie Moreno.

The Ohio senator said he expects the Trump-Vance ticket to win.

“Look, I feel good,” Vance said. “You never know until you know, but I feel good about this race. I felt good about my own race a couple of years ago when I voted in this exact same spot. Hopefully it goes as well for President Trump and me as it went for me a couple of years ago in the state of Ohio.”

Asked what he’d like to say to voters, about half of whom will be disappointed with the results of the presidential election, Vance said, “I think my attitude is the best way to heal the rift in the country is to try to govern the country as well as we can, create as much prosperity as we can for the American people and remind our fellow Americans that we are all fundamentally on the same team however we voted.

"I certainly hope you vote for Donald J. Trump today. I think that his policies are going to promote peace and prosperity for our citizens. But if you vote the wrong way, in my view, I'm still going to love you.

“I'm still going to treat you as a fellow citizen. And if I am lucky enough to be your vice president, I'm going to fight hard for your dreams and for your family over the next four years."
